Hey there!
If a cost of a gallon recently doubled, then it increased by 50%. This is because half of 100% is 50% and it takes one more 50% to double.
Hope this helps you.
Have a great day!
Answer: options B,C, and E are correct
Step-by-step explanation:
Made a 100% on the test
We have constructed two angles with angle measures, 30° and 50° respectively.
Recall the angle sum of a triangle is 180°; the formula for angle sum of any n-sided polygon is formulated by: 180(n - 2), where n is the number of sides.
Since we need the three angles to equal to 180, we can call the third angle x.
Hence, our equation becomes:
x + 30 + 50 = 180
x + 80 = 180
x = 100
Thus, our third angle is 100°
